All the dangers of 'slushies' after under-sevens warned not to drink them

Parents have been warned that children under seven should not drink slushies because they can pose a serious health risk.

Slush ice drinks are a popular choice to keep cool in the summer,with machines found in beachside cafes and amusement arcades up and down the country.

But the Food Standards Agency (FSA) has now warned under-sevens shouldn’t drink slushies at all – and those aged between seven and 10 shouldn’t drink more than 350ml of the drink per day.

The agency warns that if a child drinks several slushies in a short space of time they can be exposed to ‘very high’ levels of glycerol.

This can cause shock,very low blood sugar levels and loss of consciousness.

What is glycerol intoxication?

Glycerol is a food additive also known as glycerine or E422. It is used in slushies to prevent the liquid from freezing totally solid.

Glycerol intoxication occurs when someone consumes too much glycerol in a short space of time. As its effects are related to body weight,and glycerol itself is generally of low toxicity,children are at the highest risk of intoxication.

At very high levels of exposure,glycerol intoxication can cause shock,a sudden sharp drop in blood sugar (hypoglycaemia),a build-up of acid in the blood (metabolic acidosis),or loss of consciousness.

If a child becomes unwell with headaches,nausea or vomiting soon after drinking a slushy,the caregiver should immediately give them drinks or food containing sugar and call 111 for medical advice.

If the child becomes drowsy or confused,call 999.

In the last three years,there have been nine confirmed cases of glycerol intoxication in young children which required hospital treatment in the UK. A further seven potential cases were reported in the media.

The FSA says parents should avoid slushy products if they are unsure about the ingredients.

The agency has also asked retailers to no longer offer free slushy refills to children under 10 years of age,and told manufacturers to use the minimum amount of glycerol needed to achieve the frozen effect.
